Metallographic Techniques, Part 2

Metallography is the science that descirbes the constituiton and structures of metals by using microscopy. Metallography is used in almost all stages during the lifetime of a component, from the intial materials development to production, manufacturing process control and even failure analysis when required. Good metallographic techniques are essential to obtaining accurate results in the analyses. The modern specium preparation procedures involve sectioning, mounting (cast and compression), grinding, and polishing. In this self-guided digital course, students will learn - with the help of rich visuals, narrated amimations, demonstration videos and interractive quizzes - the various metallographic techniques involved in the specimen sampling and preparation.

Metallographic Techniques, Part 2 talks about the different parts of microscope and discusses the various techniques that can be used to measure and quantify the microstructural features of a specimen.
